Which statement best describes the primary aim of Quality Assurance in a safety-critical industry?

• A. Detecting defects after production.
• B. Preventing defects from occurring.
• C. Allowing occasional defects if costs are high.
• D. Fulfilling paperwork requirements only.

Answer: (B)

Preventing defects from occurring is the main aim of Quality Assurance in safety-critical industries. QA focuses on building quality into the process—from robust procedures and training to process controls and ongoing improvement—so mistakes and failures are prevented before they can impact safety. In environments where harm is possible, catching problems after they happen leaves risk and costly consequences, so the proactive approach of QA is essential. While checks and documentation have some value, QA isn’t about inspecting after the fact or just ticking boxes; it’s about designing and maintaining processes that ensure reliable, safe performance from the start. Allowing defects if costs are high or focusing only on paperwork would miss the core goal of preventing unsafe outcomes.
